Bargle was a male shrew who temporarily acted as Log-a-Log while Redwall Abbey was beseiged by Marlfoxes after the murder of the previous Log-a-Log by Fenno. It was Bargle who told Dippler that Fenno killed Log-a-Log.
Bargle saw the spirit of Martin the Warrior, who warned Redwallers about the attack of Marlfoxes and their allies. He died defending the wall from Raventail when the Marlfoxes secretly attacked.
